- I have recently purchased a 12" Dobsonian on an
alt az mounting. With my previous equatorial mounting
I found it easy to find objects by working out
their hour angle from their RA and local sidereal time.
<br>How do I work out the altitude of an object using the
local sidereal time? I cannot seem to find the equation
in my books.<br><br>Regards,<br><br>Stuart
- The SEDS site has a short list of Messier
Marathon locations where people will congregate to count
the Messier Objects.<br><br>If you would like to join
a group and do it check out this
